From 1e572aa5686a6871eee7840e227f86e474cc7c2a Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Wed, 25 Jan 2017 00:52:22 +0530 Subject: usb: musb: constify musb_hdrc_config structures Declare musb_hdrc_config structures as const as they are only stored in the config field of a musb_hdrc_platform_data structure. This field is of type const, so musb_hdrc_config structures having this property can be made const too.
